How can PLC Designer be completely removed from a PC?
Answer:
Uninstalling PLC Designer:
Uninstall PLC Designer (e.g., Lenze PLC Designer Setup 4.1.0 in the software list; Settings --> Apps --> Installed Apps)
If available: Uninstall the service pack for PLC Designer in the software list
For PLC Designer V3 only: Manually delete the installation directory, as some files were not uninstalled (e.g. C:\Program Files (x86)\Lenze\PlcDesigner\3.14.0.133).
Optional: Delete PLCDesigner repository
PLC Designer V3: All data in C:\ProgramData\Roaming\Lenze\PlcDesigner
PLC Designer V4: All data inC:\ProgramData\Roaming\Lenze\PlcDesigner4
The repository will be rebuilt when PLC Designer is started for the first time, provided that the data is installed in Easy Package Manager.
Please note: If you delete the PLC Designer repository, all libraries and device descriptions that you have installed yourself will be deleted. Please skip this option if you want to keep them.
Please note that the ProgramData directory is hidden and may not be displayed in Windows Explorer. In this case, you must set the Windows Explorer options to display hidden directories.
Optional: Delete option files
For each version of PLC Designer, there is a subdirectory "UserOptions..." in C:\Users\<username>\AppData\Roaming\PLCDesigner
The corresponding subdirectory can be deleted
Please note that the AppData directory is hidden and may not be displayed in Windows Explorer. In this case, you must set the Windows Explorer options to display hidden directories.
All data in C:\ProgramData\PlcDesigner
Please note that the ProgramData directory is hidden and may not be displayed in Windows Explorer. In this case, you must set the Windows Explorer options to display hidden directories.
The default settings will then be used in PLC Designer.
Delete the Windows temp directory
Open thedirectory %temp% in Windows Explorer (Windows Explorer input line).
All files and directories in this directory can be deleted.
If some files and directories cannot be deleted, they can be skipped.
Reinstalling PLC Designer:
Preparation
It must be ensured that the user has the necessary rights. Ideally, the user should be logged in with administrator rights.
Any virus scanners (except Windows Defender) should be deactivated for the duration of the installation or installation of PLC Designer should be added as an exception.
In addition, these exceptions can be added in Windows Virus & Threat Protection:
The PLC Designer setup should not be started from a directory that is synchronized via OneDrive or other cloud services. The setup can be started from C:\temp, for example.
Execution
Now you can start the new installation of PLC Designer (e.g., Lenze PLC Designer Setup 4.1.0.exe).
